FLYING RULER

Flying Ruler is a tape measure, ruler, protractor and a goniometer (angle-measurer). It is four devices in one app, providing you with the quickest way to measure a distance or an angle.

The Flying Ruler app allows you to measure in the most original way: by just moving your device from one point to another.

The secret of the program is that it is based on the principles of the inertial navigational system (INS): the position of the device is determined with the help of the accelerometer and the gyroscope.

The app has different modes so you can choose which mode is better and easier to use on each occasion. You can measure with the body of the device in one mode or with a virtual ruler in another. You use the same methods to measure angles as the app allows you to measure angles both on a surface area and between surfaces through space.

The app also allows you to save a measurement by taking a photograph of the measurement and mark the place that was measured.
